WATCH.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed March 11, 1915. Serial No. 13,593.

To all whom it may concern Be it known that I, CHARLES L. DEPOL- LIER, acitizen of the United States, residing in the borough of Brooklyn of thecity of New York, in the county of Kings, in the State of New York, haveinvented certain new and useful Improvements in atches, of which thefollowing is a specificat-ion, reference being had to the accompanyingdrawing, forming a part hereof.

This invention relates particularly to stem-winding and stem-settingwatches. It is well known that retail dealers in watches receive manycomplaints concerning ladies watches to the efiect that the watch willnot run and must be replaced by a good one. The cause of the complaintis usually that the watch has not been wound and has stopped because ithas run down. In the case of wrist watches and other miniature watchesthe failure to wind the watch is often-times to be attributed justly tothe necessarily small size of the crown which must be rolled between thefingers in order to wind the watch. When this crown is very small and ispartly inolosed by the bow it is often-times very di'flicult to grasp itso that it is rotated with certainty.

It is the object of this invention to overcome this difficulty and theobject is accomplished by making the bow itself, which is easilygrasped, rotatable for the purpose of winding the watch.

It would be undesirable to let the bow be pulled out for the purpose ofsetting the hands of a watch and provision is therefore made whereby thepulling out of a central arbor and crown efl'ects the necessary couplingbetween the bow and the setting device to permit the setting to beaccomplished by rotation of the bow.

The invention will be more fully described hereinafter with reference tothe accompanying drawing in which it is illustrated and in which Figure1 is a detail view, partly in section, showing so much of a watch as isnecessary to enable the application of the invention thereof to beunderstood. Fig. 2 is a detail view in section on the plane indicated bythe line 22 of Fig. 1.

The watch-case center a is bored to receive loosely, so that it shall becapable of rotation, a radial sleeve 1) which is provided at its innerend with a flange or external shoulder b to bear against the innersurface of the center around the hole. The sleeve 1) projects beyond thecenter and has tightly secured thereto, outside of the center, a ring orcollar 0 to which the usual bow cl is secured, preferably by pivotscrews d as shown. Within the sleeve 6 and near its outer end is tightlysecured a sleeve 6 which is formed with an axial, polygonal hole 6', inwhich fits freely, as it has to be capable of endwise movement, thearbor f which has its upper part polygonal in cross section to conformto the hole 6.

On the outer end of the arbor f is secured the crown g which forms asuitable finish for the end of the arbor and also furnishes a hold bywhich the arbor 7 may be pulled out to a limited extent for the purposeof setting the watch. The lower or inner end of the arbor 7 is guided ina suitable bearing and is adapted as usual for engagement with thewinding and setting devices, which it is not necessary to show anddescribe, since they may be of any usual or suitable construction.Spring jaws h of the usual character are provided to cooperate as usualwith a beveled portion of the arbor f for the purpose of retaining ityieldingly in one position or the other.

It will now be seen that the bow d is at all times connected operativelywith the arbor 7 so that the arbor may be rotated by grasping the bow,whether the arbor is in its inner position for winding the watch or inits outer position for setting the watch, and that while the bow is notmovable radially with respect to the watch, the arbor f may be movedradially for the purpose of effecting operative engagement with thewinding mechanism or the setting mechanism as may be desired.

It will be obvious that changes in details of construction andarrangement may be made to suit different conditions of use and that theinvention, therefore, is not limited to the particular details shown anddescribed herein.

I claim as my invention 1. In a watch, the combination of a watchcasecenter, a sleeve passing radially through said watch-case center androtatable therein, a bow secured externally to the outer end of saidsleeve, and a winding arbor mounted axially within said sleeve andoperatvely engaged thereby.

2. In a watch, the combination of awatchcase center, a sleeve passingradially through said Watch-case center and rotatable therein, saidsleeve having at its inner end an eX ternal flange or shoulder, a boWsecured externally to the outer end of said sleeve, and a Winding arbormounted axially within said sleeve and operatively engaged thereby.

3. In a Watch, the combination of a Watchcase center, a sleeve passingradially through said Watch-case center and rotatable therein, a bowsecured externally to the outer end of said sleeve, and a Winding arborradially movable Within said sleeve but operatively engaged thereby soas to be rotated therewith.

4.. In a Watch, the combination of a Watchcase center, a sleeve passingradially through said Watch-case center and rotatable therein, a bowsecured externally to the outer end of said sleeve, a second sleevesecured Within the first named sleeve and having a polygonal holetherethrough and a Winding arbor having its outer portion polygonal incrosssection to conform to said hole so as to be movable radiallytherethrough but to be ro tated therewith.

5. In. a Watch, the combination of a Watchcase center, a sleeve passingradially through said watclrcase center and rotatable therein, a bowsecured externally to the outer end of said sleeve, a Winding arbormounted aXially within said sleeve and operatively engaged thereby andmovable axially therein and a crown secured to said arbor outside of theend of said sleeve.

This specification signed and witnessed this third day of March, A. D.,1915.
